Abstract
Evolution of the electronic absorption and photoluminescence spectra of the fullerene C-60 solutions with various concentrations in a polar solvent (N -methylpyrrolidone) was studied. Comparison with the electrooptical propert ies of these solutions shows that a slow (associative) fullerene-solvent in teraction mechanism is operative at large (nearly saturating) concentration s (1 x 10(-3) g/cm(3)), whereas the solutions of relatively low concentrati on (less than 5 x 10(-4) g/cm(3)) exhibit fast complex formation between fu llerene and the solvent molecules. The latter interaction significantly cha nges the electronic structure of fullerene. (C) 2000 MAIK "Nauka/Interperio dica".
